A coin operated delivery system for manual dispensing of products from vending machines. The system, being manually operable and of relatively simple construction, is intended for use in low volume sales locations where the use of large expensive electrically operated vending machines cannot be justified because of insufficient sales volume. The system comprises an elongated open top horizontal channel in which is disposed an elongated helix of substantially the same length. The coils of the helix are widely spaced apart to receive the individual items of product to be dispensed between the adjacent coils. The helix is linked to a rotatable coin receiver mechanism. Upon insertion of a coin, the coin receiving mechanism and the helix may be rotated through one full rotation to force the unit of product contained in the outermost coil of the helix to be discharged from the channel. The system is adaptable to vending of products whose purchase price may be represented by one or more coins of appropriate denomination.
